One amazing fact we’ve already learned from the Democratic presidential candidates’ debate, now airing live on MSNBC from South Carolina: Mike Gravel is running for president!!!

OK, for those unwilling to visit his Web site: age 76; former U.S. Senator from Alaska (1969-1981); known for having put into the public record the Pentagon Papers in 1971; trailing in the polls behind “none,” “other,” and “unsure.”
